sounds like she's just crying out for attention. If you could do a lot mommy/daughter outings -- doesn't have to be expensive - - rides, window shopping outingsm, etc........she'd see that she's not being put on the back burner. Sounds like she needs to be given more responsibility with helping out with the baby - - asking her if she'd be willing and able to perform 'paid' baby sitting responsibilities, for example, might give her a 'place' in the new family.
